The influence of low-frequency magnetic field on plasma antioxidant capacity and heart rate.
This animal study exposed Sprague-Dawley rats to a 40 Hz, 7 mT time-variable magnetic field and measured ECG heart rate and plasma antioxidant capacity before and after exposure, including after 14 days. The authors report a significant decrease in heart rate after 14 days. Antioxidant defence findings were mixed, with an increase reported for 14-day exposure in one condition and a significant decrease reported for 60 minutes over 14 days.
Key points
- Rats were exposed to a 40 Hz, 7 mT low-frequency magnetic field for 30 or 60 minutes.
- ECG heart rate and plasma antioxidant capacity were measured before exposure, after a single exposure, and after 14 days.
- A significant decrease in heart rate was reported after 14 days of exposure.
- Antioxidant defence results were mixed across exposure-time conditions over 14 days.
- The authors conclude that exposure time influences heart rate and plasma antioxidant capacity.
- The abstract does not report sample size or detailed statistical results.
